HARRY H. PLATT, LABOR ARBITRATOR

Services will be today for Harry H. Platt, a labor arbitrator who decided the landmark case on residency requirements for Detroit police officers.

Mr. Platt died Saturday in Oakland, Calif., where he recently had moved from the Detroit area. He was 83.

In 1975, Mr. Platt upheld the city of Detroit's position that members of the police department must live in the city. Later that year, the Supreme Court issued a similar ruling.

A native of Russia, Mr. Platt moved to Detroit in 1911 and attended what is now Wayne State University, and later the University of Michigan Law School. He practiced law for 56 years.

Mr. Platt was former director of the Detroit Bar Association, and chairman of committees of the State Bar of Michigan and the American Bar Association. Since 1926, he was active in the Allied Jewish Campaign, and was a former member of the board of directors of the Jewish Vocational Service and Family Service.
